LISTSERV is not going to add headers to the email to support a
certain character set just so it can add a bottom banner, because
doing so may mess up the message, which may have been sent
using a different encoding scheme. So you can make the bottom
banner such that it will match the encoding scheme of most
messages that pass through, but any message using a different
encoding scheme may garble the bottom banner.


> Not if properly labeled, and properly interpreted at the client side.

That's a problem too, because not all clients interpret it correctly
even if properly labeled. Some clients simply don't support certain
encoding schemes, and some mail transfer agents chop off the 8th
bit on 8-bit characters. There's nothing that the sender or
LISTSERV can do about that -- those are just the facts of life on
the Internet. More and more clients DO support most encoding
schemes and fewer and fewer MTA's mutilate 8-bit characters, but
there is no way to guarantee either.
